A condensed ('executive summary') version of Business in Binondo, possibly plus other bits of information gathered from here and there. A kind of meta-directory of Binondo.

Obviously incomplete, but have to start somewhere. Fortunately, it looks like there is no time limit on editing/updating a post. Not sure that the Shop Directory sub-forum of Building Materials forum is the right place for this post -- why not Tools or Home Appliances or Electronics, etc.? You get into problems like this with hierarchical classification systems.
